An embodiment is directed to a hardware circuit for performing operations on data transmitted between a processor and memory. The hardware circuit includes a first interface communicatively coupled to the processor. The first interface configured to emulate a first protocol of the memory. The hardware circuit further includes a second interface communicatively coupled to the memory. The second interface configured to emulates a second protocol of the processor. The hardware circuit also includes hardware logic configured with a bi-directional path, such that each of the first and second interfaces is associated with a different direction of the bi-directional path. The bi-directional path is configured to execute an operation on data received at both the first interface and the second interface.

Fast XOR interface with processor and memory

The present disclosure describes systems and methods for improving the safety of bio-implantable electronics systems used for recording and electrical stimulation applications. The present disclosure discusses a communication protocol that provides DC balanced, bi-directional communication between a controller hub and satellite electrical stimulation and recording devices distributed throughout the patient's body. The present disclosure also describes a system for detecting and preventing current leaks along electrical pathways that may pass into a patient.

Integrated power delivery, communication, and health monitoring system for implantable electrode

Systems and methods are disclosed herein for recording electrical signals in the presence of artifacts. The system and methods can employ multiple techniques for attenuating large, unwanted artifacts while preserving lower amplitude desirable signals. Aspects that can improve the recording of electrical signals in the presence of larger artifacts include particular electrode placement and spacing, high dynamic range amplification with good linearity, and signal blanking. Combinations of more or fewer techniques can be employed to achieve the desired attenuation of signal artifacts while preserving the desired signal. The systems and methods are suitable for recording neural signals in the presence of electrical stimulation signals.
